SPECIFICATION forming part of Letters'Patent No. 720,331, dated February10, 1903.

' Application filed May 19, 1902. V Serial No. 107,985. (No model.)

To aZZ whont it may concern:

Be it known that I, CARL RODNEY CULLEY, a citizen of the United 'States,residing at Norwalk, in the county of Huron and State of Ohio,haveinvented certain new and useful Improvements in Printing-Presses;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and. to the characters of reference markedthereon, which form a part of this specification.

This invention relates to multicolor-printing presses, and particularlyto rotary perfecting-presses of that kind.

The main object of the invention is to form a perfecting-machine whichwill print in sev eral colors on both sides of the paper simultaneously.

A further object is to form such a press to take and print from a rollof paper, avoiding hand-feeding and permitting continuous operation, thesheets being out after printing.

A further object is to form a rotary press with which a series ofimpressions may be made of any desired size without waste of paper. Thisobject is effected by an intermittent feed and a construction whichpermits the web'to rest after each impression until the cylinders haverotated to the printing-point of the next impression.

With these and other objects in'view a press embodying the invention ishereinafter described, and is illustrated in the accompanying drawings,in which Figure 1 is a diagrammatic side elevation of the press. Fig. 2is a side elevation, parts being removed. Fig. 3 is a similar endelevation. Fig. t is a side elevation, the driving gear-wheels beingremoved to show camopera'ted devices to bring the form and impressioncylinders together. Fig. 5 is a front view of the feed mechanism.

Speaking generally, the press consists of a main cylinder having bothform and impression surfaces, and minor impression and form cylinderscorresponding, respectively, to the form and impression surfaces of themain cylinder. The number of form and impression surfaces on the maincylinder and the number of minor form and impression cylinderscorrespond to the number of colors desired, and the press is-not limitedto any specific number of colors.

The machine illustrated in the drawings has four printing-couples andwill print two colors on each side, and the frame is indicated at 6, themain cylinder at 7, and the minor cylinders at S, 8 8, and 8, saidcylinders being mounted on shafts in suitable bearings in the frame ofthe machine and are driven from the shaft 9 of the main cylinder bygearwheels 10 on the various shafts. Any proper means of driving themain shaft 9 may be used.

The circumference of the main cylinder in this machine has four equaland equidistant parts 7*, 7 7, and 7 the length of each of which isone-fifth of the circumference of the main cylinder. Of thesesurfaces 7indicates the form forone colorand 7 the form for the other color forone side of the paper, and 7 and 7 are respectively impres'sion-surfacesfor the form-cylinders 8 and 8, which print the two colors on the otherside of the paper.

8 and 8 are impression-cylinders for the forms 7* and 7 Fourprinting-couples are thus produced, two for each side of the paper, thecourse of which through the press is indicated by adotted line inFig. 1. The spaces 7 between the form and impression parts are for thetympan-hooks, form-clamps, 8 &c., and their aggregate length is equal tothat of one of the form and impression parts, thereby forming theremaining fifth of the circumference of the main cylinder.

The minor cylinders are spaced an equal distance apart around thecircumference of the main cylinder, and the circumference of each ispreferably equal to one-fifth of the circumference of the main cylinder,although this equality is not essential. They revolve, 5 however, fivetimes to once of the main cylinder and print at every fifth revolution.They have a simultaneous reciprocal radial movement with respect to themain cylinder, so that each comes into contact with the com- IOOplementary portion of the periphery of the main cylinder duringone-fifth of the rotation of the latter and is forced out to miss thesame during the remainder of its rotation. To effect this, thebearing-blocks 8 of the minor-cylinder shafts slide radially in guides6, forming a part of the frame of the machine, and the shafts areconnected by rods 11 to a vibrating disk 11, which is loose on the mainshaft. The disk is operated by a lever 12 of the third class, which isfulcru med to the frame at 12, pivotally attached to the disk at 12*,and has a roller 12, which runs in a cam-groove 13 on the cam-disk 13,which is fast on the main shaft. The lever is bent to bring the point ofits attachment to the disk at a right angle to the roller with respectto the shaft, so as to give the disk a throw equal to the eccentricityof the cam. When the roller is moved in or out by the cam, the leverthrows or turns the disk correspondingly, which motion is communicatedby a toggle action with the rods 11 to the minor cylinders, forcing theminto or out of contact. The motion is steadied by springs M behind thebearing-blocks. The movement, as will be understood, need only be smalland is not enough to disengage the gearing. The throw of the cam is suchthat the minor cylinders will contact only during the proper part of therevolution of the main cylinder, such part being in this instanceonefifth. The length of the rods is adjustable by screw-couplings 11".It is to be understood that the cams and connections to give the radialmovement to the minor cylinders are duplicated at each end of the maincylinder.

To ink the form-cylinders 8 and 8", any old or proper inking apparatusmay be used. I have indicated such an apparatus at 15, supported on theframe adjacent said cylinders. The inks will be different colors, asdesired.

To ink the forms '7 and 7 on the main cylinder each a difierent color,mechanism is provided to give a radial reciprocating movement to theink-rollers. The shafts of the ink-rollers 16 on each side of the maincylinderare supported in bearing-blocks 16*,which have verticaladjustment in frames 16 by thumb-screws 16. The frames 16", carrying therollers, slide radially with respect to the main cylinder in guides 17on the frame of the machine, and the motion is given through crank 17and pin 1'7 connection with a rockshaft 17 and its crank 17 by a rod 18,which has a bearing-roller 18 in an outer cam-groove 13 in the cam-disk.Such a rod and cam at opposite ends of the main cylinder operates theinkers on opposite sides of the main cylinder, respectively. The camsare so formed that when the disk rotates the respective rollers arebrought to inking contact with their respective and corresponding form,and when such form has passed the rollers of its color are forced backout of contact.

The paper web necessarily passes outside of the inkers just described,and it is threaded through the machine, as shown in Fig. 1,

around register-rolls, (indicated at 19 and 20.) It is essential thatthe length of the line of travel of the web around the register-rollsbetween each minor cylinder be an exact multiple of the length of theform being printed; otherwise the impression given at each of the smallcylinders will not register with those given at the others. This lengthis secured by making the register-rolls 19 adjustable in theirsupporting-frames. I have illustrated a construction to obtain suchadjustment, the supporting-frames for the rollers being indicated at 19,mounted on the frame of the machine and adjustable laterally by slot andbolt 19. For vertical adjustment the rolls are carried by bearing-boxes19 upon rightand-left screws 19", supported by the frames and rotatableby hand-cranks 19 through shafts 19 and bevel-gears 19. The rolls maythus be raised, lowered, or extended to bring the distance to an exactmultiple of the form. Any other means to effect the same result woulddo. In this connection I will mention that the form need not be thewhole length of the circumference of the minor cylinders, since thepaper is fed step by step, the length of each step being equal to thelength of the impression and is otherwise at rest, although thecylinders continue rotating.

The rolls 20, adjacent the minor cylinders, are so positioned that theweb is out of contact with both main and minor cylinders except duringthe impression period.

The paper is fed from a roll 21 between feed-rollers 22 on shafts 22,which are geared together and operated intermittently by a segment-gear23, which is driven by intermediate gearing from the shaft of the maincylinder and at equal speed therewith, so that the feed is equal to thetake of the cylinders. In the drawings these feed parts are shown beforethe cylinders, forming a push-feedg but they may well be placed behindthe cylinders, forming a' pull-feed, pulling the web through the press.

The length of paper fed at each revolution depends on the number ofteeth in the segment-gear, and this length is equal to the length of theform being printed. Various segment-gears having different numbers ofteeth may be used to accommodate forms of different lengths, and thesegment-gear'is so positioned that it operates the feed simultaneouslywith the impression.

Any proper means of attaching the type or printing-plates to theform-surfaces and tympans to the impression-surfaces maybe used.

Fig. 1 illustrates the press at beginning of impression. After makingready the impression-cylinders 8 and 8 are drawn in to couple with theform-surfaces 7 and 7, respectively, and the form-cylinders 8 and 8 aredrawn in to couple with the impression-surfaces 7" and 7, respectively,and the feed begins. By the contact of the couples the pato the feed.

small cylinders have completed one revolution, or the impression, theyare lifted out of contact by the cams, but not out of gear.Ccnsequently'they continue to rotate until the' main cylinder has madethe remaining four-fifths of its rotation, when they are again drawn infor the next impression.

The press is designed particularly for multicolor-work on counter-checkbooks, wherefore I have indicated a numbering-machine at X, perforatorsat W and Y, and a cutter at Z, which, however, are no part of myinvention.

My invention is not limited to the exact mechanical construction shown,and any equivalent means may be used. Additional couples for more colorsmay be provided by the addition of minor cylinders and surfaces on themain cylinder. The number of colors which may be printed is limited onlyby the number of minor cylinders and the size of the main cylinder. Thesize of the minor cylinders as compared to the main cylinder is notlimited to the one-to-five proportion described, but may be varied asdesired, with corresponding variation of speed and cams.
